SEMIAUTOMATIC BAND SAW MACHINE:     

pásová pila na kov Pegas 290x320 SHI-LR-F

290x320 SHI-LR = two cutting speeds
290x320 SHI-LR-F = three-phases electromotor with  a frequency converter  for a fluent regulation of the blade speed from 20 to 100 m/min

Semiautomatic machine with full hydraulic manipulation.
The machine is designed for cutting of material in vertical and angle cuts, angle cuts are possible to set fluently rom 45° left to 60° right.
It is suitable for piece production and small series production.  Thanks to its rugged construction it enables cutting of wide range of  profiles and full materials.

Construction:

• The machine is  constructionaly  designed in that way, so that it corresponds to standard  exertions in productive conditions.
• Arm is 25 grades sloped, it increases the lifetime of  blade. Arm is placed in adjustable bearings.
• Working positions of the arm are controlled by the cam and microswitches of the upper and down position of the arm. In the end position microswitch is on, arm goes to selected up position.
• The vice is made of cast iron and the jaws allow a safe grip. The hydraulically controlled vice with short travel is situated in an adjustable dovetail groove and is equipped by a quick clamping of material and quick clamping for side moving of vice. The adjustment is manual with a wheel and trapeze thread. Speedy jaw adjustment is achieved by means of a lever, spring and trapeze half-nut. The vice jaw travels left-right with regard the angular cut; it is secured by a crank.
• A turntable gives a big place for supportion of material and its perfect clamping. The turning table has autoarresting every 15 grades ( the groove with the spring ) General angles are adjusted by the nonius. It is possible to equip the machine by digital indication of the angle for a wish. 
• Model with STOP function – cutting : it enables to stop cutting by pressing STOP button at any time. The arm goes up with the running blade without stopping the machine and without opening the vice.
• Leading of blade in hard-metal plates.
• Automatic regulation of blade tension.
• Mechanic tightening of the blade.
• The cleaning brush for perfect cleaning and function of blade.
• Drive of machine is solved by worm gear box with maintenanceless oil filling. Three-phases electromotor with  a frequency converter  for a fluent regulation of the blade speed from 20 to 100 m/min. Termoprotection of engine.
• Cooling system for emulsion with liguid distribution to blade guides.  
• Robust base with a tank for chips.
• Indication of  blade tightening and opening of the cover
• Controlling 24 V
• The main switch is located on the front door. There is equipped with a safety button, which stops the saw. There is also a feed regulator and buttons, which control the various available movements.
• Maschine is equipped by hydraulic system that manipulates all functions of that maschine. It presses the arm to cut, pulls up the arm and opens and closes vices.

Basic equipment of machine:

• blade
• Set of spanners for common service
• measuring end stop
• manual instructions

Operating cycle:
After manual adjustment of the jaws and the arm’s operational positions the operator starts the cycle with a switch on the control panel. The hydraulic cylinder of the vice grips the material and the saw starts working. The cutting speed of the arm is controlled by a throttle valve. After finishing the cutting, the arm reaches its top operational position and the band drive stops. The vice opens and the operator can handle the material.The control system monitors correct tension of the band, correct position of the band guard and, through a diode ampere-meter the load on the band drive during operation (i.e. assists setting up the arm’s cutting speed).
